  • Pay $300 across your cards before the statement date to bring overall utilization to 30%.
  • Lenders usually see the balance on your statement, so paying before the statement closes lowers the reported ratio even if you pay in full every month.
  • Closing an unused card removes its limit and pushes utilization up; a limit increase does the opposite.

Guideline sources (checked 24 Oct 2026): US Consumer Financial Protection Bureau — “Experts advise keeping your use of credit at no more than 30 percent of your total credit limit” (reviewed 12 Dec 2024); TransUnion CIBIL — a ratio above 30% can start to drag scores down. The 10% option is simply a stricter target, not a published rule.

A credit utilization calculator for every card you hold

This credit utilization calculator works out your credit utilization ratio — the share of your available credit you are using — for each credit card and for all of them together. It also tells you how much to pay to bring the ratio down to 30%, 10% or a target you choose.

Utilization is one of the inputs credit scores use in the US, UK and India (CIBIL), so knowing the number before your statement closes helps you decide which card to pay first. Enter balances and limits in dollars, rupees, pounds or euros; you never need a card number, and nothing leaves your browser. Add as many as twenty cards, including store cards and cards with a zero balance, because unused limits count too.

How to use the Credit Utilization Calculator

  1. Choose your currency and a target: 30% (the common guideline), 10% or a custom percentage.
  2. For each card, enter its current balance and credit limit. Use “Add a card” for more cards and × to remove one.
  3. Read your overall utilization and the colour bar — the black marker is your target.
  4. Check the card-by-card table to see which balances are above the target and how much to pay on each.
  5. Copy the results if you want to keep a note before paying.

How credit utilization is calculated

Utilization = balance ÷ credit limit × 100. Overall utilization adds up every balance and every limit first: (sum of balances) ÷ (sum of limits). The amount to pay to reach a target T is balance − T × limit, or nothing if you are already under it.

Example: balances of $1,800, $2,700 and $300 on limits of $5,000, $3,000 and $7,000 give $4,800 ÷ $15,000 = 32%. Paying $300 brings you to 30%; paying $3,300 brings you to 10%. Card B is at 90% on its own, so paying it first helps both the per-card and overall ratios.

Guideline bands

The 30% figure comes from consumer guidance such as the US Consumer Financial Protection Bureau and TransUnion CIBIL in India; it is a guideline, not a cut-off in any scoring formula.

UtilizationHow it is usually described
Under 10%Low — a stricter target some people aim for
10–30%Within the commonly quoted 30% guideline
Over 30%Above the guideline; can weigh on scores
Over 100%Over the limit — fees and a stronger warning sign

Tips to lower your ratio

  • Pay before the statement closing date — the statement balance is usually what is reported.
  • Spread spending across cards rather than maxing out one.
  • Keep old cards open if they have no annual fee; closing them removes their limit.
  • If you carry balances, plan the payoff with the credit card payoff calculator and your monthly budget planner.

Credit Utilization Calculator FAQ

How does a credit utilization calculator work?

It divides each card’s balance by its limit, and the total of balances by the total of limits, then shows how much you would need to pay to reach your target ratio.

What is a good credit utilization ratio?

Under 30% is the most common guideline; lower is generally better. Paying in full every month and keeping the reported balance low both help.

Does this credit utilization calculator work for India?

Yes — choose INR. CIBIL and other Indian bureaus also consider how much of your credit limit you use.

Is credit utilization per card or overall?

Both can matter. This tool shows each card and the overall figure so you can see which card to pay first.

If I pay in full every month, is my utilization 0%?

Not necessarily. Card issuers usually report the balance on your statement, so a large bill that you later pay in full can still show as high utilization. Paying before the statement closes lowers it.

Are my card details stored?

No. Only balances and limits you type are used, and only in your browser — no card numbers are needed.
